Math 112 At Byu: Student Averages On Various Exam Questions, Makayla Mcleod

Theses and Dissertations

In Math 112 at BYU, exams play a crucial role in evaluating students' understanding of the course content. Traditionally, these exams are a combination of multiple-choice and free-response questions, with the latter serving as a means to assess a student's thought process while solving problems. Will students perform as well on a multiple-choice exam? Or will students' averages be higher on free-response exams? In this thesis, we test 7 hypotheses related to these questions to provide more insight into the answer. We examine other factors that may affect students' averages, including various Calculus 1 topics, modes of questioning, and difficulty …

Sacred Bonds: The Association Between Religious Giving And Relationship Quality, Sofia C. Suxo-Sanchez

Theses and Dissertations

Grounded in interdependence theory, we sought to understand how religious giving is associated with relationship quality by drawing on two distinct datasets, one from emerging adult couples and another from established couples. Using structural equation modeling, we tested the direct association between religious giving and relationship quality, and whether it was mediated by materialism. Our quantitative findings contrasted previous research; we did not find materialism to mediate the association and found a significant, negative association between religious giving and relationship quality. Through a team-based coding approach, we explored how and why established couples believed religious giving impacted their relationship quality. …

Investigation Of The Isbr Method With A Quad Detector For The Measurement Of Turbine Rotor Inlet Temperature, A. Cole Cecil

Theses and Dissertations

Temperature measurements at the inlet of a gas turbine inlet have proven challenging due to the high flow velocities, limited space, and high temperatures. This work investigates the use of the Integrated Spectral Band Ratio (ISBR) method to measure temperature using a new set of gas bands and a new method for collecting, measuring m and converting raw signals to digital temperature data at low cost and high speed (4 Hz). The Pressurized Oxy-Coal (POC) reactor was refurbished and used in this work to simulate turbine inlet conditions. The POC was modified to produce a stable natural gas and air …

Impact Of Telehealth On Outcomes In Daily Practice, Shannon Stuebs

Theses and Dissertations

While telepsychology has existed in various forms for years and has been researched since the 1960s (Abrams, 2020), it was not until the COVID-19 pandemic that telepsychology started to be widely used. Prior to the COVID-19 pandemic, one study found that psychologists conducted only around 7% of their work via telepsychology, a number that jumped to over 85% in response to COVID-19 (Pierce, Perrin, Tyler, et al., 2020). While there has been a significant increase in the research exploring the efficacy of telehealth since the start of the pandemic (Lin et al., 2022), further research regarding long-term impacts and specific …

With the proliferation of terrestrial and space-based wireless radio frequency transmitters and receivers in recent years, there is a greater need for spectrum cooperation and transparency. Spectrum is a limited resource that is shared between all wireless devices, both active and passive. The spectrum needs of today and tomorrow demand new techniques to enable cooperation and device transparency. This dissertation explores an innovative field, wireless sub-protocols, that provides novel software solutions for spectrum cooperation and transparency. The first application is radio astronomy. Radio astronomy deploys highly sensitive, passive RF receivers to capture faint signals from distant celestial bodies. Because passive …

The Reinterpretation Of The Round Shaker Barn: How Patriarchal Values Changed The Doctrine, History, And Architecture Of A Religion, Caroline Johnson

AWE (A Woman’s Experience)

The Shaker Round Barn in Hancock Massachusetts has long been studied for its historical significance and insight into the life and beliefs of the nearly extinct religion. Within the discipline of art history, it is one of the only Shaker buildings discussed in entry-level architecture classes, portrayed to be the physical personification of the Shaker faith. The current narrative of the Shakers has simplified not only this particular structure but the entire religion, down to a few distinguishing characteristics: their name, which came from their exuberant worshiping practices; their founder, Mother Ann Lee, being the female reincarnate of Jesus Christ; …

Teaching Verbs Of Motion In A Task-Based Russian As A Foreign Language (Rfl) Course, Joan Castellví, Elena Markina

Russian Language Journal

The paper focuses on one of the most complex topics in Russian as a Foreign Language (RFL) instruction: verbs of motion (VoM). We introduce an innovative approach to teaching these verbs, grounded in Task-Based Language Teaching (TBLT), and contrast it with the traditional approach that follows the Presentation-Practice-Production (PPP) framework, which has dominated the field until now. By analyzing a sample of widely used textbooks specializing in VoM, we show that introducing the VoM system—specifically, the sequence in which the verbs are presented—follows the PPP design and is primarily grammar-oriented. This approach is based on the concept of “directionality,” which …

Do Your Abc: Teaching Tense And Aspect With Verbs Of Motion, Irina Six

Russian Language Journal

This paper examines the continued application of a content-based approach initially developed for teaching Russian verbs of motion (VoM) at the novice level (Six). It begins by introducing the ABC principle, a method that presents prefixed and unprefixed VoM together in their most typical contexts, rather than separately. The ABC principle ("A+B+C=D", as in поплыл + плыл + приплыл = плавал) helps visualize a three-leg journey and introduces students to two distinct sets of stems: Directional stems for A, B, and C verbs, and Non-directional stems for D verbs.

The paper then explores extending the ABC principle to intermediate-level …

Russian Verbs Of Motion In L2 Acquisition: Testing The Efficacy Of A Usage-Based Approach, Tobias-Alexander Herrmann

Russian Language Journal

Unprefixed Russian motion verbs present unique challenges for second language (L2) learners as they encode distinct types of motion events. Traditional, directionality-based methods of teaching these verbs have faced criticism, prompting the adoption of alternative, cognitively informed approaches. This article builds on usage-based methodologies, such as those proposed by Nesset and Janda (2022), to investigate whether teaching unprefixed verbs of motion (UVoMs) as constructions can enhance L2 instruction. Using the frequent UVoM pair idti and xodit′ , both meaning ‘walk’, as a case study, I pursue two main goals. First, drawing on corpus data, I examine the construction UVoM + …

From Gesture To Coded Knowledge: Rediscovering And Redefining Tpr When Teaching Russian Motion Verbs In An Outdoor Classroom, Elena Susanna Weygandt

Russian Language Journal

The necessity to move my Russian as a second language (L2) classroom in an event tent during the “main” pandemic year encouraged me to create lessons engaging students’ movement and thus rediscover the Total Physical Response (TPR) method. This article presents the case for using TPR-inspired teaching as a mode to be considered in instruction of Russian verbs of motion (VoM). TPR, a teaching method and language acquisition theory suggested by James Asher in the 1960s, has further evolved in TPR role-playing and TPR storytelling and is used in L2 instruction today (e.g., Cook, 2008, p. 132; Davidheiser, 2002; Elliott …

Directionality Of Motion In Second Language Acquisition: With A Focus On L1-Korean L2-Russian Speakers, Hakyung Jung, Hyug Ahn, Jacee Cho

Russian Language Journal

This paper examines L2 acquisition of directionality of Russian motion verbs by L1-Korean speakers in terms of Slobin’s (1996) Thinking-for-Speaking (TFS) hypothesis and the markedness principle. Although directionality is lexically encoded in the verb in both Korean and Russian, the organization of this concept differs. In Russian, directionality is categorized solely by the feature [+/- directional], whereas in Korean, motion event expressions are distinguished not only by [+/-directional] but also by [+/-multi]. Experiments on L1-Korean, L1- Russian, and L1-Korean L2-Russian speakers demonstrated that (i) in Korean, the presence or absence of an explicit goal plays an important role in verb …

Introduction To The Special Issue: Searching For Alternative Approaches To Conceptualizing And Teaching Russian Verbs Of Motion: Bridging Linguistics And Teaching Practice, Maria Bondarenko

Russian Language Journal

This special issue seeks to account for the current status of an emerging trend we have observed in linguistics and L2 instruction over the last two decades: reconceptualizing Russian verbs of motion (VoM). To contextualize the contributions to the issue, in this Introduction, I will give an overview of how this trend has evolved from its inception until the present time, delineating within it two successive stages called the Cognitive Turn and Instructional Turn.

A Pedagogical Analysis Of How Unprefixed Verbs Of Motion Are Presented In Instructional Materials For Beginner Russian Language Learners, Elena Petrova, Kris Lewis

Russian Language Journal

It is well-known that verbs of motion (VoM) are quite challenging for Russian language learners. We analyze four VoM-specific pedagogical materials (three textbooks and one mobile application) for their usefulness in supporting second language acquisition and the development of new thinking-for-speaking (TFS) patterns in beginner-level Russian language learners. Focusing on directionality, scaffolding, comprehensible input, the use of visuals, and communicative activities, we highlight how these materials lay a foundation for understanding VoM but are not sufficient for helping learners fully develop new TFS patterns. We pose recommendations for future research, teaching, learning, and materials development in the area of Russian …

Feedback Parameters For A Closed-Loop Multiple-Input Multiple-Output Model Of The Upper Limb, Ian Syndergaard, Daniel B. Free, Dario Farina, Steven Knight Charles

Faculty Publications

Both closed-loop models and multi-input multi-output (MIMO) models of the neuromusculoskeletal system of the upper limb are important for simulating and understanding motor control. Yet no large-scale linear neuromusculoskeletal models of the upper limb that are both closed-loop and MIMO have been developed. The primary difficulty in creating such models is choosing appropriate feedback parameters (such as feedback gains and delays), as such a collection of parameters is not available in the literature. The purpose of this work is to 1) present a method for developing MIMO models of short-loop afferent feedback and 2) offer estimates of average feedback parameter …

Enhancing Fault Tolerance In Tmr Soft Risc-V Fpga Socs Through Failure-Driven Mitigation Strategies, Andrew Elbert Wilson

Theses and Dissertations

Field-Programmable Gate Arrays (FPGAs) leveraging soft processors, particularly those implementing the open-standard RISC-V Instruction Set Architecture (ISA), are increasingly important for space missions due to their adaptability and reconfigurability. However, their susceptibility to radiation-induced Single Event Upsets (SEUs) presents significant reliability challenges, necessitating robust fault-tolerant strategies such as Triple Modular Redundancy (TMR). This dissertation evaluates the effectiveness of TMR-based mitigation techniques for Linux-capable soft RISC-V System-on-Chip (SoC) implementations deployed on SRAM-based FPGAs operating in high-radiation environments. Using a combination of deterministic fault injection and neutron radiation testing, this work identifies critical residual single-point failure modes that persist in TMR-protected designs. …

Applying Ceragenins In Translational Medicine: Activating Mesenchymal Stem Cells And Preventing Healthcare-Associated Infections, Aaron L. Zaugg

Theses and Dissertations

Healthcare-associated infections are a major global concern. Increased infections among vulnerable populations lead to millions of deaths, annually, complicated by the emergence of multi-drug resistant pathogens. These infections are often facilitated by medical devices serving as abiotic surfaces that facilitate the formation of biofilms. Notably, colonization of prostheses and other bone-associated medical devices can lead to corrective procedures, revisions and death. To address these issues, inspiration can be drawn from natural sources of bone health and defenses against infection. Cathelicidins are endogenous peptides involved in both bone maintenance and infection control. Ceragenins are small molecule mimics of cathelicidins with broad …

Linking Static And Dynamic Structures And Properties Of Materials With Computational And Mathematical Models, (Enoch) Sin Hang Ho

Theses and Dissertations

Terahertz (THz) spectroscopy is an effective technique to study and manipulate the structural dynamics of materials, due to its frequency range being very similar to the vibrational frequencies of collective atom motions in a host of materials. High-field and broadband THz radiation can be generated via optical rectification (OR) in nonlinear optical (NLO) crystals. The efficiency of OR response in an NLO crystal is determined by many factors, including molecular hyperpolarizability (β), 2nd order electric susceptibility (χ(2)), crystal structure, primary growth orientation, refractive index, absorption and phase matching condition. In this dissertation, I will focus on using computation methods and …

Predicting Single-Leg Eccentric Hamstrings Strength In Aging Athletes Using Diagnostic Ultrasound- And Survey-Derived Parameters, Lee J. Hinkle

Theses and Dissertations

Introduction: Eccentric hamstring strength declines with age and contributes to mobility limitations. Although Nordbord testing quantifies eccentric strength, few studies have examined it in older adults, and none have predicted strength performance on this test using ultrasound or survey- based measures. Methods: We recruited 122 senior athletes (60 female) at the 2024 Huntsman World Senior Games. Ultrasound-derived cross-sectional area (CSA), echogenicity, and subcutaneous fat thickness, along with demographic and activity data, were used to predict single-leg peak force using Bayesian regression. Models were sex-stratified, and predictors were selected using leave-one-out cross-validation (LOO IC). Results: In males, CSA, age, leg side, …

Purpose: Determine if the previously reported exaggerated systolic blood pressure response to daily activity and moderate exercise amongst hypertensive adults could be accounted for by differences in fitness. Methods: 30 normotensives adults (15 low fitness control (LFC) and 15 high fitness control (HFC)) and 15 unmedicated adults with ambulatory hypertension (HTN) participated in this study. Participants completed 24-hour ambulatory blood pressure monitoring (ABPM). Lactate Threshold (LT) and estimated ����̇O2max were determined for each participant. A week later, blood pressure was measured while participants completed 5-minute bouts of treadmill exercise at fixed absolute intensities (2.5 mph 0% and 12% grade) and …

Characterization Of Ultra-High-Speed Friction Stir Welds Made In Thin Sheet Aa6061-T4 Material, Todd Grant Lainhart

Theses and Dissertations

Friction stir lap welding (FSLW) of thin aluminum sheets in industry and in research has faced challenges in weld quality that limit welding speeds. Interfacial defects such as hooking and thinning are common defects that appear at the interface of FSLW, and researchers and process operators have traditionally reduced process parameters such as feed rate and spindle rotation to fully eliminate the defects. While such measures are successful in creating fully consolidated FSLW, feed rates for FSLW have stagnated around 1 mpm with the fastest feed rates recorded at 3 mpm, making it difficult for manufacturers to implement FSLW in …

Computational Advances For Single-Cell Proteomics, Hannah Boekweg

Theses and Dissertations

The overarching goal of biologists is to characterize biological systems. When the workings of a system are understood, they can be fixed, broken, preserved, mimicked, and even replicated. The field of proteomics seeks to characterize systems through the lens of proteins. Proteins are referred to as the 'workhorse' of the cell to illustrate that they perform most functional tasks within the cell. These tasks are highly varied, including enzymatic activity, structural support, transport, storage, cell signaling, gene regulation, immune response, and more. Proteomics has been instrumental in new biological discoveries by characterizing the functional state of cells. A new area …

Quantum-Chemical Modeling Of Mechanisms And Selectivity In Open-Shell Organometallic Reactions, Michael T. Davenport

Theses and Dissertations

Quantum mechanical calculations have emerged as a powerful approach for directly evaluating reaction mechanisms and selectivity in transition metal-ligand complexes involving organometallic intermediates. Density functional theory (DFT) quantum mechanical methods enable the generation of potential energy surfaces and structures that define reaction mechanisms and allow for the evaluation of selectivity through statistical transition state theory. However, in certain cases, it is necessary to go beyond statistical treatments and incorporate atomic motion through molecular dynamics simulations. Additionally, many transition metal-mediated reactions involve unpaired electrons and spin state crossings. This dissertation focuses on the application of DFT-derived potential energy surfaces and molecular …

This literature review examines the clinical characteristics, correlation with other psychological and neurological disorders, and treatment options for various BFRBs. A search of APA PsycInfo and PubMed databases yielded 74 sources, 13 of which have been used in this review. Clinical characteristics of BFRBs include emergence during childhood and adolescence, influence of other psychological disorders, self-awareness, biological sex, internalizing and externalizing behaviors, high levels of …

Rapid Beamformer Weight Calibration Update Method For The Advanced L-Band Phased Array Camera For Astronomy (Alpaca), Kayla Lyman Ward

Theses and Dissertations

The Advanced L-Band Phased Array Camera for Astronomy (ALPACA) is a phased array feed instrument designed for the Green Bank Telescope. It is capable of producing 40 real-time beams on the sky, widening the telescope's field of view and significantly increasing survey speed. ALPACA employs an RF-over-fiber (RFoF) signal transport system from the phased array feed front end to the digital backend. This RFoF link is expected to introduce phase delays and changes in gain through out the course of an observation, invalidating the beamformer weights previously calculated. This work presents rapid beamformer weight calibration updates for ALPACA, a method …

A Missionary's Memoirs: Mongolia Revisited, Isaac Smith

Undergraduate Honors Theses

This is my story. It is a very personal story, but one that I want to share with others. Although it takes place predominantly in Mongolia, it is not merely a story about Mongolia, or even the Mongolian people. It is not really even a story about me. What is it then? It is a story about faith and love. It is an attempt to better understand how the gospel of Jesus Christ intricately fits into people’s lives all over the world—even in Mongolia. It is a compilation of essays, of memoirs, of my experiences. It is a story about …
